Siemens 5SY6332-8CC Three-Phase Circuit Breaker

Siemens 5SY6332-8CC is a three-pole miniature circuit breaker from the SENTRON family, rated for 32 A and 400 V AC, designed to protect three-phase distribution and motor circuits in industrial and commercial panels. It uses a D-curve tripping characteristic for short-overload and motor inrush scenarios and provides a rated breaking capacity of 6 kA (Icn) at 400 V AC. The device is built for quick assembly on compatible panels and features an IP20 enclosure with connected conductors, a depth of 70 mm, and a rated insulation voltage of 440 V while operating at 50/60 Hz. The unit is designed for up to about 10,000 mechanical switching cycles. Typical applications include protecting three-phase feeders in control cabinets, machine rooms, and distribution boards where reliable overload and short-circuit protection is required.
